BABBEL-LINING MACHINE.

Application filed January 11, 1927. Serial No. 160,899.

This invention relates to a machine for the moduction of barrel linings such as are shown in my co-pending application Serial No. 38.701, filed June 22, 1925. My mprm'ed barrel lining has a body portion which is longitudinally corrugated so that the lining can readily accommodate itself to the shape of the barrel, and thls body portion is non-stretchable longitudmally so that it is more or less stiff in the direction of its length and will hold its shape and position within the barrel until the liningis filled with the contents. One end at least of the barrel lining is rendered flexible in all directions by double creping it so that the end which is thus double creped may be readily folded over. -If desired, the lower end of the lining may also be rendered flexible in all directions as well as the upper end which is to constitute the mouth.

The aim of the present invention is to provide an improved, practical machine for economically producing barrel linings of the kind.

In the accompanying drawing, wherein I have shown, for illustrative purposes, one of the many embodiments which the improvements of the present invention may take:

Figure 1 is a plan view of my improved machine;

Fig. 2 is a side view thereof; and

Fig. 3 is a view showing a barrel lining such as is disclosed in my said application Serial No. 38,701.

Referring to the drawings in detail, the frame of the machine may be of any suitable construction, but it is here illustrated as having two side frames 10, 1O tied together by braces or rods 11. The roll of paper 12 is supported on a shaft 13 journalled in suitable brackets 14 located at 'one end of the frame. A drag is exerted on the paper roll by means of a stra 15 secured to a rod 16 and carrying a weight 17.

The paper web 18 is drawn forwardly over a roll 19 from which it passes downwardly into a tank 20 and under the rolls 21. The water in this tank may be heated by steam coils 22. The wet paper then passes upwardly, as at 23, and onto a cylinder 24 upon which the corrugating and creping operations are performed, as hereinafter described more in detail. The cylinder 24 isfixed to a shaft 25 supported in suitable brackets 26. The shaft 25, together with the cylinder thereon, is driven in a clockwise direction from a main shaft 28 through a pinion 29 and a gear 30. This drive shaft is suitably journalled in the frame and may .have a drive pulley 31. The gear 30 meshes with a gear 33 fixed to a shaft 34 journalled in slidably bearing boxes 35 behlnd which are springs 36, the pressure of which may beadjusted by screws 37. On this shaft is a rubber faced roll 38 which is pressed against the paper by the springs 36 as the paper passes between this roll and the cylinder. This roll 38 is preferably co-extensive with the crinkling cylinder 24 and servesto squeeze excess water out of the paper and cause the paper to adhere to the crinkling cylinder. Above the roll 38 and fixed tothe shaft 39, journalled in slidablebearing boxes 40, is a roll 41 which is pressed against the crinkling cylinder by springs 42 located behind the bearing boxes .40. These springs may be adjusted by the screws 43. 44-is a doctor blade which will be described hereinafter more in detail. After the paper web has been corrugated and crinkled, as hereinafter described, the web is carried away from the machine by a belt 45.

In accordance with the present invention, the crinkling cylinder 24, the foll 41 and the doctor blade are so constructed and arranged that the body portion of the web is transversely corrugated, as at 50, and at least one marginal or edge portion of the web is corrugated in the direction of the length of the web and is cross crinkled so that the edge or margin, or edges or margins, as the case may be, are flexible and stretchable in all directions. wherein is illustrated a machine whereby the barrel linings produced are flexiblein In the present instance,-

all directions at both ends, as at 51, the cylcircumferentially corru ated portions, the

cylinder is longitudinal y corrugated. The circumferentially corrugated portions of the cylinder are designated by the character 24, and the central longitudinally corrugated portion by the character 24*. Furthermore in the present disclosure, the circumferential ribs of the ortions 24 are grooved or corrugated in t c direction of the length of the c linder and in registry with the corrugatlons of'the portion 24" so that, in effect,

there is provided, on each end of the roll, rel in which the lining is to be positioned. G"

A barrel lining of this sort is relatively stiff,

circumferential rows of projections. .The cylinder 24 is preferably made of chilled iron but may be constructed of any other suitable material. The roll 41 is corrugated len thwise in accordance with the longitudlnally extending corrugations of the cylinder so that the roll 41 and the cylinder mesh, so to speak, with the result that the wet web, as it passes between this roll and the cylinder, is transversely corru ated, that is to say, the corrugations on t e roll 41 cause the paper to assume the longitudinally corrugated shape of the cylinder. The doctor blade is provided, at each end, with a serrated portion 44 which is adapted to cooperate with the circumferentially corrugated portion 24 of the crinkling cylinder. By serrating the ends of the doctor blade, teeth are provided which project into the grooves between the circumferential corrugations or ribs on the crinklingcylinder.

The portion 44 of the doctor blade, and

which portion is located between the serrated portions 44, is out of engagement with ,the crinkling cylinder and the paper carried thereby.

The operation of the machine is briefly as follows: The paper is drawn throu h the tank 20 and onto the crinkling cy inder against which it is firmly pressed by the rubber faced roll 38. This roll causes the web to adhere to the cylinder and presses excess water from the web. The cylinder carries the paper web between itself and the corrugated roll 41 with the result that the paper is forced into the longitudinally extending grooves in the crinkling cylinder whereby the web is transversely corrugated.

The cylinder then carries the paper up against the doctor blade, with the result that the edge or marginal portions of the web are crinkled transversely of the longitudinally extending corrugations which have been formed in these marginal edges. The marginal portions of the web are thus double crinkled, so to speak, that is .to say, they are rendered elastic and flexible in all directions, and the body or central portion of the web is longitudinally corrugated but is not crinkled.

In Fig. 3, I have shown, by way of illustration, one form of barrel lining which may be made by the use of the present machine. In this instance, the lining is shown as having both ends double crinkled, but it is within the spirit of the invention to double crinkle but one end and, preferably, that end which is to cover the mouth of the barin its body portion so that it will retain its shape when placed in a barrel until it is filled and, since the end portions are flexible in all directions, they may be readily folded over. The body portion of the lining may expand radially or laterall so as to take the form of the barrel when t e lining is filled. I claim as my invention: 1. In a paper creping apparatus of the character described and in combination, a supporting surface provided with a longitudlnally corrugated portion and a transversely corrugated ortion, means for causing paper to take the shape of said surface, and a blade cooperating with the transversely corrugated portion whereby the paper passing thereover is crinkled.

2. In a paper creping apparatus of the character described and in combination, a cylinder having a portion of its periphery longitudinall corrugated and a second portion circum erentially corrugated, and a doctor blade cooperating with the circumferential corrugations for crinkling the paper carried upon such portion.

3. character described and in combination, a cylinder having a portion longitudinally corrugated and a portion at one end provided with circumferentially corrugations, a roller cooperating with said cylinder for forcing the paper 1nto said corrugations, and a doctor blade cooperating with the circumferentially corrugated portion of said cylinder for crinkling the paper carried thereby.

4. In a paper creping apparatus of the character described and in combination, a cylinder having a longitudinally corrugated portion and a portion at one end provided In a paper creping apparatus of the with circumferential corrugations, means WILLIAM A. LORENZ.
